[Buildd-tools-devel] Bug#355880: Segfaults immediately until I remove /etc/dchroot.conf

Package: schroot
Version: 0.2.6-1
Severity: normal

        Hi,

 schroot provided a nice dchroot wrapper when I installed it, but it
 segfaulted immediately.

 bee# gdb ./schroot/dchroot
 [...]
(gdb) run
Starting program: /tmp/s/schroot-0.2.6/schroot/dchroot

(gdb) print this->ruid
$1 = 0
(gdb) print this->uid 
$2 = 0

 I didn't understand what code should be initializing this->ruid and /
 or this->uid, you probably know better.

   Cheers,
